Description
MD 4 VARIO select is a three-stage VARIO diaphragm pump intended for laboratory vacuum applications. It operates on 200-230 V at 50-60 Hz and is supplied with a CH power cable for straightforward connection in corresponding electrical environments. The compact membrane-pump design supports reliable vacuum generation in research, analytical and process-support settings where oil-free operation is preferred. Net weight is 19,400 kg and gross weight 22,100 kg, reflecting a robust yet manageable laboratory instrument. This model forms part of the VARIO select series from manufacturer VACUUBRAND and is delivered as a complete single-unit package ready for integration into existing lab workflows. The three-stage configuration provides the staged compression typical of multi-stage diaphragm technology, making the unit suitable for a range of common laboratory evacuation and solvent-handling tasks. Country of origin is Germany. The pump is classified under laboratory equipment and arrives as one piece, allowing immediate installation once the CH mains connection is available.

Questions about MD 4 VARIO select, CH
What is this article?
MD 4 VARIO select, CH is the article on this page. Luminix Health distributes Vacuubrand for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Lab instruments.
A laboratory vacuum pump lowers pressure for filtration or evaporation. A diaphragm pump tolerates solvent vapour better than an oil-sealed rotary vane pump, and it reaches a milder vacuum. The ultimate vacuum and the flow, and whether the wetted path survives the solvent, are the choices.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
